Glass is rigid, brittle, an amorphous solid made of lustrous material made by ingenious fusion of silica. It transmits sound energy at its resonant frequency and at low frequencies. 
Its resonance changes with thickness. It vibrates like a drum head when its body meets equal frequencies. It’s own acoustic space and sound reflections - glass transmits a lot of sound energy. It also disperses and multiplies … How similar we are as bodies to those materials.

I love glass as a material. Its natural character, its physical transformation from viscous to solid, the flux and the quick act of shaping/sculpting it in seconds. There is no time to overthink when one works with fire and results can be completely unexpected. This one burst into pieces in the glory hole after making a perforation. It is a one work piece that is not possible to re -reproduce. Therefore, the analogy with orgasming it's quite straightforward …

The unexpected, the uncontrollable, the intensity, the sweat, the fire, the breath.
